- 中文摘要: The X-ray diffraction data of cubic BN were reanalyzed by aspherical electron charge distribution model. The valence-charge densities of nitrogen atom and boron atom were represented by a finite multipole deformations. A least-squares refinement of the model charge was computed by fitting population parameters and thermal parameters. The result showed that there is a tendency toward a ionic bond in going from IV-IV compounds to III-V compounds.
